IPC: B65H75/24
Filed: 1987-07-13
Granted: 1991-04-03
Abstract: An axially deformable yarn carrier tube comprises in its outer surface a plurality of rows of radial, slot-shaped perforations 1 which are arranged next to one another in the circumferential direction and whose longitudinal axes enclose an angle  alpha  in the range between 20 and 50 DEG  with an outer surface line running in the circumferential direction, the perforations overlapping at their ends. The solid outer surface sections 2 between the radial perforations 1 are of web-shaped design and by applying radial pressure to the carrier tube, with deformation in the circumferential and axial direction, can be brought into mutual abutment in the region between the ends of the perforations 1, these ends being left open. As result of the deformation of the web-shaped outer surface sections 1, the carrier tube is shortened in the axial direction and the axial shortening of the carrier tube is limited by the mutual abutment of the web-shaped outer surface sections 2. <IMAGE>

These compositions are made up of a safe and effective amount of an active pharmaceutical permeant contained in a novel penetration-enhancing vehicle comprising, (i) a cell-envelope disordering compound; and (ii) a lower alkanol selected from the group consisting of ethanol, propanol and isopropanol and mixtures thereof. The weight ratio of cell-envelope disordering compound to lower alkanol is between about 50:1 to 1:50 and preferably between about 9:1 and 1:9. Preferred cell-envelope disordering compounds are oleic acid, oleyl alcohol, glycerol oleates, methyl oleate, methyl laurate and mixtures thereof. The novel penetration enhancer vehicles are non-irritating to the skin and enhance the penetration of a broad spectrum of pharm aceutical permeants including hydrophilic salts. ell-envelope

Granted: 1993-08-18
Abstract: In a high-speed fiber-optic tranmission system, data streams are synchronized using fixed stuffing before being multiplexed for transmission. The fixed stuffing information is replaced with forward error correction (FEC) information, whereby FEC is effected without any increase in transmission speed. FEC information blocks of each data stream can be synchronized to the frame timing of the transmission system, or they can be relatively unsynchronized. In the latter case, an FEC decoder acts in a self-framing manner to synchronize itself to the FEC information blocks of the respective data stream.

Abstract: A multipurpose functional fluid which is comprised of a major amount of a hydrocarbon oil and a minor amount, sufficient to improve characteristics of the fluid of a novel additive. The aditive is comprised of a calcium salt complex, a group II metal dithiophosphate salt, a borated epoxide and a carboxylic solubilizer. The calcium salt is preferably in the form of an overbased calcium sulfonate salt, the antiwear agent is preferably in the form of a zinc dithiophosphate salt, the borated epoxide is preferably the reaction product of boric acid and a 16 carbon 1,2-epoxide and the carboxylic solubilizer is preferably in the form of a reaction product of an acylating agent containing a substituted hydrocarbyl-based substituent containing about 12 to 500 carbon atoms. Other components such as viscosity improvers and anti-foaming agent are generally present in the fluid. The resulting fluid has improved low temperature fluidity and filterability, improved EP/antiwear performance, excellent friction improving properties, antichatter capability as well as being capable of passing hydraulic/transmission tests, power steering and brake capacity tests. These features are maintained simultaneously without harming other desirable performance characteristics of the fluid. The EP/antiwear performance characteristics are maintained concurrently with the anticorrosion characteristics and transmission performance capabilities. The improved water tolerance is maintained concurrently with the improved EP performance characteristics.

Abstract: In coded speech communication, discrete speech samples are analyzed to generate a first signal indicating the fine pitch structure of the speech samples and a second signal indicating their spectral characteristic. The amplitudes and locations of main excitation pulses are determined from the fine pitch structure and spectral characteristic and a third signal indicating the determined pulse amplitudes and locations is generated. The difference between the speech samples and the main excitation pulses is detected and used in auxiliary excitation pulse calculation to determine gain and index values of auxiliary excitation pulses by retrieving stored auxiliary excitation pulses from a code book so that the retrieved auxiliary excitation pulses approximate the difference. The first, second and third coded signals and the gain and index values are transmitted through a communication channel to a distant end where a replica of the main excitation pulses is recovered from the received first and third signals and a replica of the auxiliary excitation pulses is recovered from a code book in response to the received fourth signal. These replicas are modified with the second signal to recover a replica of the original speech samples.
